Thiolate-bridged diruthenium complexes such as [Cp*RuCl(mu 2-SR)2RuCp*Cl] (Cp* = eta5-C 5Me5; R = Me, nPr, iPr) and [Cp*RuCl(mu2-SiPr)2RuCp*(OH 2)]OTf(OTf = OSO2CF3) promote the cycloaddition between propargylic alcohols and cyclic 1,3-dicarbonyl compounds to give either the corresponding 4,6,7,8-tetrahydrochromen-5-ones or 4H-cyclopenta[b]pyran-5-ones in high yields with complete regioselectivity.

The circular dichroism of (-)-2-methyl-4-phenylbutyric acid was investigated, and a comparison was made with (-)-2-phenylpropionic and (-)-2-methyl-3-phenylpropionic acids.It was shown that the position and magnitude of the Cotton effect in the region of 220 nm are determined mainly by the distance between the chromophores and not by the proximity of the asymmetric center to one of the chromophores.

13031-04-4, Name is 4,4-Dimethyldihydrofuran-2,3-dione, belongs to tetrahydrofurans compound, is a common compound. Computed Properties of C6H8O3In an article, once mentioned the new application about 13031-04-4.

The influence of support acidity and basicity was investigated in the enantioselective hydrogenation of methyl benzoylformate and ketopantolactone on cinchonidine-modified Pt/Al2O3-SiO2 and Pt/Al2O3-Cs2O catalysts. Two series of flame-derived 4.7 wt.% Pt/Al2O3 catalysts in which the acid-base properties of the support were systematically varied by introducing SiO2 (5-80 wt.%) or Cs2O (0.25-10 wt.%) were applied. Addition of SiO2 improved the enantioselectivity with a maximum at 30 wt.%. Enantioselectivity correlated well with the acidity of the catalysts characterized by TPD of NH3 and with the selectivity to hydrogenolysis of methyl cyclohexyl ketone to ethylcyclohexane. On the contrary, doping with Cs was detrimental to the formation of the (R)-alcohols and the drop in enantioselectivity could unambiguously be attributed to the basicity of the support characterized by TPD of CO2. The critical impact of support ionicity on the electronic properties of Pt, and thus on the adsorption and interaction of the reaction components on the metal surface, was further proven by the good correlation between the enantioselectivities of all catalysts and the ratio of CO adsorbed in bridged to linear (B/L) geometry. The practical importance of our findings is demonstrated by the best ee (94 ± 0.5%) achieved so far in the industrially relevant hydrogenation of ketopantolactone to (R)-pantolactone.

Synthetic Route of 87392-07-2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.87392-07-2, Name is (S)-Tetrahydrofuran-2-carboxylic acid, molecular formula is C5H8O3. In a Article，once mentioned of 87392-07-2

A comparative study on the kinetic resolution of racemic amines (2,3-dihydro-4H-1,4-benzoxazine and 1,2,3,4-tetrahydroquinoline derivatives) via diastereoselective acylation with N-tosyl-(S)-prolyl chloride and its structural analogs was performed. The effect of resolving agent structure on the stereoselectivity of heterocyclic amine acylation was examined. The highest stereoselectivity was achieved in the case of acylation with acyl chlorides bearing a conformationally restricted pyrrolidine ring and an aromatic substituent in the protecting group at the nitrogen atom.
